Low porosity ceramics for thermal barrier coatings

DOI: 10.1615/thermopedia.000173

Let us consider the radiative properties of zirconia ceramics produced by a plasma-spraying technology. This ceramic is widely used as a thermal barrier coating to provide thermal insulation and to protect metallic turbine-engine components from hot gas streams (Bose, 2007; Markosan et al., 2007; Golosnoy et al., 2009). The low thermal conductivity of the ceramic makes it possible to considerably decrease the temperature at the metal-ceramic interface even in the case of a small coating thickness (~0.1-0.5 mm). There are many other actual and potential industrial applications of yttria-partially-stabilized zirconia ceramics (Liang and Dutta, 2001; Bose, 2007). In many cases, one of ...
